Keeping The Lid On BOG
Malaysia LNG plant orders Siemens compression solutions
The Petronas Bintulu liquefied natural gas (LNG) complex in Sarawak, Malaysia, has ordered Siemens turbo compressors and mechanical drive gas turbines to re-liquefy boil-off gas (BOG) from LNG storage tanks.
Siemens said the project will deploy the world’s first gas-turbine-driven cryogenic-temperature BOG turbo compressor, recapturing gas that otherwise would have been flared, increasing LNG production and reducing carbon dioxide emissions.
The company will provide a tandem-casing, cryogenic-temperature BOG turbo compressor and a single-casing LNG-refrigerant turbo compressor, both of which will be direct-driven by Siemens SGT-700 mechanical drive gas turbines.
The SGT-700 handles high nitrogen content as it burns natural gas with up to 40% N2 (nitrogen) content. Siemens said its solution reduces the installation space of the rotating equipment significantly.
The equipment will be delivered by April 2014, with plant start-up scheduled for October 2014.
